Understanding the pathogenesis and the typical imaging features of carotid artery web, and accurately diagnosing the carotid artery web will help to implement targeted intervention for cryptogenic stroke and reduce the recurrence of stroke events. Carotid web (CW) can be defined as an endoluminal shelf-like projection often noted at the origin of the internal carotid artery just beyond the bifurcation. It is recognized as a possible cause of ischemic stroke in young adults. We describe here a case of ischemic stroke caused by a CW in a healthy man. Detection of this vascular abnormality required the use of computed tomography angiography. CW is a specific anatomical structure. Its imaging and clinical manifestations are different from atherosclerosis. It's also is a latent etiology to cryptogenic stroke. CW should be considered in patients with otherwise cryptogenic stroke, otherwise healthy patients presenting with stroke and without the typical risk factors for atherosclerotic carotid disease and stroke.
了解颈动脉壁的发病机制和典型影像学特征，准确诊断颈动脉壁，有助于对不明原因性卒中实施针对性干预，降低卒中事件复发率。颈动脉壁（carotid web，CW）可定义为位于颈内动脉起始部，在分叉部之外的腔内呈架子样突起。它被认为是年轻人缺血性卒中的可能病因。我们在此描述了一例由 CW 引起的健康男性缺血性卒中。该血管异常的检出需要使用计算机断层血管造影（computed tomography angiography）。CW 是一种特定的解剖结构。其影像学和临床表现不同于动脉粥样硬化。它也是隐匿性卒中的潜在病因。对于其他不明原因性卒中、无典型动脉粥样硬化性颈动脉疾病和卒中危险因素的健康患者，出现卒中时应考虑 CW。
